IMPROVEMENT lN EMBOSSING AND FINISHING WOVEN FABRICS.

Specification forming part of Letters Patent No. 25,980, dated November 1, 1859.

To all whom it may concern:

Be it known that I, WALTER RALs'roN, of the city of Manchester, in the county of Laocaster and Kingdom of England, engraver to calico-printers, have invented new and useful Improvements in Embossing and Finishing bowls of paper or other substance, and by means of gearing well known to mechanics I give the circumference of the pattern roller a quicker motion than the circumference of one of the bowls, so as to obtain africtional action upon the surface of the fabric, as well as pressure, so that if the fabric is moved transversely when fed to the machine an indefinite number of watering patterns may be given to the fabric atone operation or passage; but if two operations be given moire antique or other varieties may be obtained, which can be still further varied as desired, according to the number of times the fabric is allowed to pass through the machine.

In addition to thevariety of pattern, a bright finish or luster is given to the fabric by means of the friction or rubbing action of the two surfaces of the roller and bowl. I may also obtain the same result by reversing the arrangement and causing the circumference of the bowl to move quicker than the circumference of the roller, so as to obtain a similar frictional or rnbbin g action, the gearing being simply required to be adapted for the purpose.

It is well known that for calendering purposes plain or polished rollers have necessarily been driven at a greater speed than the bowl or bowls; but hitherto it has not been considered practicable to give pattern -rollers the same relative movement.

As the machinery or apparatus used in my invention is not new in its general construction, I disclaim any right or title thereto, my invention consisting of giving the circumference of the pattern-roller a quicker motion than the circumference of the bowls, or causing the circumference of the bowl to move quicker than that of the roller, so as to obtain a frictional action upon the surface of the fabric, as well as pressure, by which I obtain a variety of patterns; but

I claim- Theemploymentofgrooved,fluted,engraved, milled, or otherwise indented rollers of metal, wood, or other suitable material, driven at a greater speed than the bowl or bowls connected with them, so as to exert a rubbing or friction upon the fabric subniitted to their action, and thereby produce an indefinite variety of pattern, as well as a bright finish or luster, and also reversing the operation by giving the bowl a quicker motion than the pattern-roller.

Dated at Manchester this 12th day ofAugust, 1859.

WALTER RALSTON.
